This invention relates to window construction,more'particularlyto a means for shifting a window sash to open and closed posi- 1 tions, and has forits object to provide, in a p 5 manner as hereinafter set forth, a shiftlng mechanism for expeditiously shifting'a sash to and for maintaining it in open position, as

well as for maintaining the sash in closed position when occasion requires.

Further objects of the invention are to provide, in a manneras hereinafter set forth, a window sash shifting mechanism which is simple'in its construction andarrangement, strong, durable, compact, thoroughly efiicient 15 in itsnse, conveniently operated, readily installed with respectto the sash and comparatively inexpensive to manufacture,

With the foregoing and other objectsin view theinvention consists of the novel con- 2 struct1on, comb1nat1on and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but;it is. to be understood 1' that changes, variations and modifications can be resortedlto which fall within the scope of the-claims hereunto, appended. I

In the drawings wherein like reference characters denote, corresponding "parts throughoutthe several views V H 1 .Figure 1 is a vertical sectional view of a window of atype including a hinged sash showing the adaptation therewith of a shifting mechanism "in accordance with this inthe sash extended to open position.

Figure 2 isa view similar to Figure 1 with the sash pivoted at its center and showing the adaptationfltherewith of a shifting mecha nism in accordancewith this invention. 7

' Figure'3 is a vertical sectional view of a modified form. of widow includinga hinged sash providedwith side pieces to constitutea coal chute and showing the adaptation withthe window of a shifting mechanism in accordance with this invention and further illustrating the sash inclosed posit on.

Figure 4 is a view similar to Figure 3 and "illustrating-the sash extended to open positionto providea coal chute} Figure 5 is a front elevation ofthe construction shown in Figure 3.

shifting mechanism in accordance with thls invention and as shown in each of the views of the drawings includes a rock shaft 1 of cyl ndrical cross section; Y I 7 The shaft 1, centrally thereof, is formed with a laterally disposed handle member 2. See Figure 5. The shaft is journaled in a pair of spaced, combined hangers and supports to be presently referred to. Each combln'ed hanger and support is of substantially L-shaped; contour. The combined hangers and supports will be suitably designated with respect to the several figures of the drawlngs to be presentlyreferred'to.

The shaft 1 at each end thereof is provided with a right angularly disposed crank armof the desired length and of cylindri'cal cross section. Both crank arms are illustrated in Flgure 5 and are indicated at 3, 4:. But one ofthe crank arms is shown in Figures 1, 2; 3 and 4 and in such figures, the 'crank arm is des1gnated3. Each crank arm at its outer end is formed with an outwardly directed, right angularly disposed extension '5providmg a combined pivot and coupler for a fiat link 7 The links 7 have their rear ends pro vided with openings 8 throughwhich pass the extens1ons5; The links 7 are of'th'e de; sired length and each has its" outer end prov ded'with an opening .9 for the passage of a pivot 10. The pivotslO are to be carried by the sashes to be presently referred to. 7

Referring to Figure 1 of the drawin s 11 denotes a window frame formed wit an' Opening 12 adapted to be closed by a sash 13,

' a '12. As shown in Figure lthe link 7 is mount ed on a pivot 10 connected to sash 13 near the bottom thereof. 'It' is to be understood that a pair of links 7 and crank arms 3' will be em- 100 ployed the shifting mechanisrn shown in disposed an upward inclinationi If the handle 2' is swung to the posltion shown in Figure 1 and thatlsuchymechanism will be as shown in Figure 5, other than that the combined hangers and supports 16 will be reversely arranged with respect to the combined hangers and supports 17shown in F lgure 5. Below the sill portion .15, that part of the frame 12 whichis' nd c dat Wi l'be. .9 5

With reference to Fig-M612 the frame 20? provides an opening which is closed 21 mounted at its tI'ZlIlSVGIISQIIlGCllLIl upon a pivot rod 22, the latter. he ng securedto frame 20;

c Thebottom of the frame 20 is providedwith a plurality of spaced',.combined supports and;

ang s fer-t e s a l.y: On o hich is shown and is indicated at 23; the arrangementb ingth s mea ei omb n ppcr s and hangers shown in Figure 1.

When the shaft 1- isrocked in a direction wherebyJthe-handlemember 2 thereof will project forwardly, shown in, F gures 1 and 2,} the crank arms 3 will be 'carried m a.

like directioni'to extend the links/T5 0 that the v sash 13 will be projectedto open position.

This statement also applies to the sash 21. The-weight of the sashbearing on the l nks Twill depress the crank arms 3 and as these latter engage the frame the sash 13 can-notibe closed. To close the sa$hf1310r 2O-the handle memb r 2. is w ng t the d t d lln p tion sh wninF-igures 1 and-2 and when in, suchposition the parts will. be so arranged as o p eve t he Opening of the a 1 91* 2 Un thev nd e memb r 2'is wu gv1n an;
